So my 10+ year old Battery Tender gave up the ghost the other day. I've had 3 Battery Tenders on my bike and multiple cars over the past 20 years, and have had 2 fail within that time, and figured it was time for something different. After doing some research, CTEK comes up frequently as a recommended maintenance charger, and I decided to get one. Found a coupon posted on the 'net for 20% off at Amazon, which sealed the deal. (Amazon was also kind enough to send me a coupon AFTER I had made my purchase. LOL.)

So, I figured I'd share with anyone who may be considering a CTEK purchase from Amazon - 20% off plus free shipping:

I will love to use that coupon if you are willing to provide DIY video for our community.
Thanks for a fantastic saving.

I don't have a DIY unfortunately. It's not too difficult to hook it up - it comes with both clamps that you can hook up to the + & - either under the hood, or directly to the battery in the trunk, and also eyelets so you can directly hook up to the battery for a more permanent installation. Both are connected to the charger with a fused quick connect/disconnect.

So which model is the best to get? I believe my car has a AGM battery.

I went with the 3300, since my intention is to use it as a maintenance charger for a seasonal car with an AGM battery (Optima Yellow Top) that doesn't get much use. Currently, however, the older Battery Tender (the last one of the 3 that I have) is still hooked up. The 7002, although it has more features and a larger charging current capacity, was unnecessary for me. Also, the ability for the 7002 charger to charge faster than the 3300 wasn't needed either, since I have a jump pack if the situation warrants.

I just hooked up my first "smart" trickle charger, the CTEK 3300 (I just received it yesterday from Detailer Domain's recent sale).

It took about 24 hours to fully charge at AGM setting!

I don't use DRLs, barely use the radio, and always lock immediately upon exiting the vehicle to put her to sleep quickly. Well, dang, I'm going to charge at least every couple of months I think, maybe even more frequently. She is my fun car.

Gonna charge the truck battery next.

I highly recommend picking up a charger if most drives are short, and that's coming from a Southern Californian!
